|
|||
* The -s option will result in an aggregate summary of file lengths being displayed, rather than the individual files.
|
||||
* The -h option will format file sizes in a "human-readable" fashion (e.g 64.0m instead of 67108864)
|

The du returns three columns with the following format:
|
||||
|
||||
size disk_space_consumed_with_all_replicas full_path_name
|

Example:
|

|

* `hadoop fs -du /user/hadoop/dir1 /user/hadoop/file1 hdfs://nn.example.com/user/hadoop/dir1`
